Those who deride plastic grocery bags as single-use items either do not own a dog or do not clean up after their dog. Policies that decrease plastic grocery bag usage are counterproductive. The many responsible dog owners will buy large numbers of previously unnecessary plastic bags at far less cost per bag than a 5-cent deterrence charge. Ever hear of the law of unintended consequences?
